A New Beginner" is someone just starting out - knows NOTHING about chess and asks questions like "what does the horsey do?" In our club we use the term "Novice" for a player who has learned all of the rules as well as the concepts of checkmate and stalemate. Such players often get hung up on the en passant capture rule, so we let them into Novice class even if they didn't quite get that rule. You could have different levels of Novice; we find it convenient to have two. Graduation to Intermediate is the point at which we expect participation in rated tournaments, i.e. they have learned tournament rules and sufficient skills to have a sporting chance against others of that class. Advancement beyond that is based on tournament experience / rating - we make this in 200-point increments, as in the USCF class system. Back in the day of the Samurai, you might keep your white belt until it gradually turns black from the huge number of times you have been knocked into the dirt. But not in modern America - parents demand to see rapid signs of "progress." So we have a rainbow of different colored belts, or classes E, D, C, B, etc.
